Ankit Singh is a second semester masters student studying High Integrity Systems at Fachhochschule Frankfurt am Main University of Applied Sciences. He is working on developing an analyzer scanner module and remote control for various scans. The scanner module uses Nmap scripts to scan targets over SMB protocol, extracts information to an XML file using JAXB, and stores it in a database. Key Nmap scripts being used include smb-brute.nse for guessing credentials, smb-os-discovery.nse for determining OS and system info anonymously, and various SMB enumeration scripts for users, shares, sessions and more. He is creating a DaNe plugin for remote control of the CAS server side scans.

- 1. Ankit Singh Masters Student (second Semester) in High Integrity System Fachhochschule Frankfurt am Main University of Applied Sciences
- 2. Working on Analyzer Scanner Module and developing remote control for various scans
- 3. Development using following softwares: * Linux Ubuntu 9.10 * Java development Kit: Sun Java 6 * Eclipse for RCP/Plug-in Developers * Nmap 5.21 * JAXB 2.1.10 (Java Architecture for XML Binding)
- 4. Stages/Flow of the Scanner module: Scanner (Nmap scripts) -> XML Doc -> JAXB -> Database
- 5. Using Nmap Scripting Engine (nse) for extracting information of the systems in the network. Targeting Server Message Block ( SMB , also known as Common Internet File System, CIFS) traffic, which is a Windows protocol.
- 6. SMB traffic is normally sent to/from ports 139 or 445 of Windows systems.
- 7. Various given SMB scripts given by Nmap to be used for Scanning the network: smb-brute.nse, smb-enum-sessions.nse smb-security-mode.nse, smb-check-vulns.nse , smb-enum-shares.nse, smb-server-stats.nse, smb-enum-domains.nse, smb-enum-users.nse, smb-system-info.nse, smb-enum-groups.nse, smb-os-discovery.nse, smbv2-enabled.nse, smb-enum-processes.nse, smb-psexec.nse
- 8. smb-brute.nse: This script is specifically targeted towards security auditors or penetration testers. Attempts to guess username/password combinations over SMB, storing discovered combinations for use in other scripts.
- 9. Usage :
- 10. sudo nmap -sU -sS --script smb-brute.nse -p U:137,T:139 <host> -oX <filename.xml>
- 11. smb-check-vulns.nse: Check for vulnerabilities in the system
- 12. This is one of the dangerous Script to Run and more likely it will bring down the server.
- 13. Not recommended to use in Production environment.
- 14. smb-os-discovery.nse: Attempts to determine the operating system, computer name, domain, and current time over the SMB protocol
- 15. This is done by starting a session with the anonymous
- 16. account (or with a proper user account, if one is given -- likely doesn't make a difference); in response to a session starting, the server will send back all this information.
- 17. Enumeration SMB scripts : smb-enum-sessions.nse , smb-enum-shares.nse, smb-enum-domains.nse, smb-enum-users.nse, smb-enum-groups.nse, smb-enum-processes.nse These scripts responsible for: Pulling a list of processes from the remote server over SMB.
- 18. Enumerates the users logged into a system either locally or through an SMB share.
- 19. Attempts to enumerate domains on a system, along with their policies.
- 20. Pulls a list of processes from the remote server over SMB.
- 21. Attempts to enumerate the users on a remote Windows system, with as much information as possible
- 22. DaNe Plugin CAS Server Side Remote Control
- 23. Thank You
